It looks like this issue was already solved by Richard Purdie in file
meta/classes/utility-tasks.bbclass in change "utility-tasks: Set T to alternate
location during do_clean".
If do_clean's log is in alternate location then nothing interferes with
oe.path.remove of temp directory under ${WORKDIR}.
This fix is probably much better than my own fix: I replaced in
/utility-tasks.bbclass function do_clean "oe.path.remove(dir)" for ${WORKDIR}
by "os.system("rm -rf %s" % (dir))".
Cheers,
Michael
